Jesus Christ, the Head

Notes:

Jesus Christ is the head.
1. The head, the cornerstone upon which everything is built
2. The head, the leader, chief in position and authority
3. The head, the one in charge to whom others submit
4. The head of the body providing nourishment, guidance, and direction to the individual members

The head, the cornerstone
Ephesians 2:20
having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone,

The cornerstone (or foundation stone or setting stone) is the first stone set in the construction of a masonry foundation. This is important since all other stones will be set in reference to this stone, thus determining the position of the entire structure.

The head, the leader, chief in position and authority
At the right hand of God, Jesus has been placed as head over all power and authority.
Matthew 28:18-20; Colossians 1:15-20; 2:10; Ephesians 1:19-23; 2:13-22

The head, the one in charge to whom others submit
Ephesians 5:22-24, 31-32 -- Two become “one flesh” -- “one body”. This is a great mystery (a reference to Christ and the church). Romans 6:12-18; 7:1-6

The head of the body provides nourishment, guidance, and direction to the individual members.
Romans 12:4-5
1 Corinthians 12:11-27 -- Through the one and same spirit
Ephesians 5:15-16 (verses 17-32 - “...if you have heard him and have been taught in him”)
Colossians 2:18-19 (verses 20-23; 3:1-17)
